One of the first K-dramas I ever watched and I almost never finished it.
I liked the female lead and her mother's relationship as it portrayed pretty well the different sides of a same story. As always I did expect the characters to be a bit more honest with each other and with themselves instead of making assumptions all the time, whether it be between mother-daughter or male-female leads.
The acting is passable and the kissing scenes made me so uncomfortable as it seemed awkward (but again, as it can be a lot of the time in K-dramas). But what I liked the least what the plot: the first part of their reunion relies on harassment and childish comebacks and even though they already knew each other, I still think it's very weird to be so personal and to force yourself in their private life (aka someone you had a one-night-stand with three years ago and just met again after all this time). Plus the female character is so obedient, it hurts my heart to see her so ''submissive'': I get there is a hierarchy between a boss and their employees but come on, sometimes it looked a lot like exploitation more than just punctual overtime hours. I'm surprised not more reviews pointed that out.
To watch if you're looking for something very light-hearted and if a bit of unrealistic romance and chara development don't bother you.
